Freeradius DHCP - strange behavior [SOLVED?]

[Kamil Jońca]

Finally all my devices works, but it is *against* warning from logs.

I have had:
--8<---------------cut here---------------start------------->8---
listen {

    type = dhcp
    ipaddr = *
    src_ipaddr = 192.168.200.200
    port = 67
    interface = lan
    broadcast = yes

}
--8<---------------cut here---------------end--------------->8---

I commented out "interface = " line, and now everything works,
regardless of
--8<---------------cut here---------------start------------->8---
Sat Nov 12 20:28:28 2016 : Warning: You MUST set "interface" if you have "broadcast = yes"
Sat Nov 12 20:28:28 2016 : Debug: (7) DHCP: Reply will be broadcast as no interface was defined
--8<---------------cut here---------------end--------------->8---
in logs.

With "interface = lan"
there were no "DHCP-ACK" for some devices (and it was my fault when
sending previous mail)


I am still not sure if it is freeradius issue or my routing, arp or
sth.

Alan asks about system:

--8<---------------cut here---------------start------------->8---
uname -a
Linux alfa 4.4.0-1-amd64 #1 SMP Debian 4.4.6-1 (2016-03-17) x86_64 GNU/Linux

sudo getcap -v /usr/sbin/freeradius
/usr/sbin/freeradius = cap_net_bind_service,cap_net_admin,cap_net_raw+ei
--8<---------------cut here---------------end--------------->8---

" cap_net_bind_service" and "cap_net_raw" is probably unneccessary.
